They're Not the Only Ones Who Resentful…

It was only evening, but the outside world seemed to be in the middle of the night. Dark shadows flitted past the windows, and the atmosphere in the carriage became increasingly oppressive…

Harry stood frozen and frozen, his whole body bathed in cold sweat.

Hermione, also frightened, suddenly remembered that the new Defence Against the Dark Arts professor was in the carriage, and turned to look.

Lupin stopped pretending to be asleep and stood up. He looked out of the window and noticed the dark figures gathering around him.

"You're too reckless, Hales. There are a lot of Dementors out here, and they hold grudges!"

"They're not the only ones who hold grudges…" Ivan muttered as he tossed the potion book aside. As the Dementors continued to gather around him, all he could think about were the things that made him angry and bitter.

"What do you want to do?" Lupin asked, frowning.

"To keep them away, of course!" Ivan said sharply.

He had forced the release of the Soul Catcher to increase his mastery level. The Patronus Charm had been upgraded from level four to level five, which meant that emotional fluctuations would no longer affect his use of blood magic.

The hordes of Dementors that had been hovering in the air were getting restless. They could tell that there was good food below, and they were furious that one of their own had been killed.

A swarm of Dementors descended from the sky, a dark mass, the temperature dropping, and the faint sound of crying could be heard outside, indicating that some minor wizard had broken under the pressure…

One of the Dementors at the front of the group managed to get through the window, but before it could take a breath, it was knocked away by a white light.

"Expecto Patronus!"

As Ivan chanted the incantation, more white mist drifted out, forming a huge light barrier that enveloped the entire carriage and continued to spread.

Several Dementors collided with the light barrier, creating ripples. The light barrier made of white mist was very strong and did not show any signs of breaking. Instead, the white mist corroded the Dementors' bodies.

The Dementors were undaunted. As they gathered, the relatively dispersed white mist began to falter.

Lupin gripped his wand, ready to lend a hand if Ivan couldn't hold out any longer, although he was reluctant to be seen with his Patronus…

Ron and Hermione both looked nervously at the sky, fearing that the Dementors would tear through the barrier and come for them.

Ivan waved his wand unhurriedly, and nearly half of the white mist escaped from the barrier and gathered around him. With a loud hissing noise, the Dementors that had been diving towards him scattered in terror…

Although there were many Dementors on patrol, Ivan's Unicorn's Shadow was not an ordinary Patronus. It was like a natural enemy to Dementors. Once a Dementor was hit or trampled by a Unicorn, it would be severely injured and become much more transparent…

Ivan drove the Dementors away from the Hogwarts train, with no intention of killing them. Dementors worked for the Ministry of Magic, and killing too many of them would be a slap in the face.

A white blur appeared in the sky, chasing after a large group of Dementors.

However, due to the white barrier, it was difficult to see clearly. One could only make out a slight outline… This was also Ivan's intention.

Hermione was relieved to see this, and Lupin sighed.

"I didn't think you could summon your Patronus at your age."

The strength of Ivan's Psalter was beyond Lupin's imagination, and he estimated that while he could also drive out these Dementors, he would not be able to do it as easily as Ivan.

"It's not that hard to learn," Ivan said, shaking his head.

In his third year, Harry learns this spell and successfully summons a Patronus.

In Harry Potter's fifth year, many of his students were able to do so after a period of practice.

Ron's urgent voice suddenly filled the carriage.

"Harry, what's wrong? Harry?"

Yvonne turned and saw that Harry had lost consciousness and fallen to the side, looking very pale.

Lupin's expression also changed slightly, and he stepped forward to inspect the room. He then breathed a sigh of relief and spoke to the worried Hermione and Ron.

"Harry's fine, he's just temporarily knocked out by the Dementors, let him rest…"

"But why didn't we pass out?" Hermione asked curiously, having had the impression that Harry was not such a fragile creature.

"Dementors suck away pleasure and bring back memories of all the painful things that have happened, so those who have had painful experiences are under more pressure than the average person…" explained Ivan.

"Yes, as Hars said, Harry was in a coma because he had been through something terrible, and there's no shame in that…" Lupin sighed as he watched Harry suffer in his sleep.

Ron nodded, and Hermione glanced thoughtfully at Ivan, thinking of his reaction to the Dementor.

At that moment, there was a rush of footsteps outside the door.

A short while later, two middle-aged wizards in uniform appeared in front of the carriage with hostile expressions on their faces. The leader of the group glanced around the carriage and his gaze stopped on Lupin.

"Who released the Patronus just now?"

"Mr. Aurors, it's me!" Ivan looked at the two of them fearlessly. He understood that these two wizards were Aurors accompanying them to supervise the Dementors.

Dementors were, after all, evil, chaotic creatures, and the Ministry of Magic could not have left them alone in the event of a massed attack.

"You?" The stout Auror Captain looked at Ivan in bewilderment, then at Lupin with a strange expression.

He found it hard to believe that a thirteen or fourteen-year-old young wizard was capable of expelling so many Dementors, and he immediately suspected that Lupin was trying to get away with it by making a young wizard take the blame.

Under their strange stares, Lupin smiled helplessly. This was not his doing.

Ivan didn't reply. He waved his wand, creating a white mist, and a calm and peaceful atmosphere filled the room.

The two Aurors then turned to face the young wizard in front of them. Although Ivan did not display his Patronus, it was enough…
